Soper) Presentation and update regarding the Oro Valley Water Utility water quality monitoring and testing program and the recently completed Consumer Confidence Reports. Click here for March 2010 Consumer Confidence Report System 10-175 Click here for March 2010 Consumer Confidence Report System 10-164 Chair Powell introduced Charles Soper Lead Operator for Water Quality. Mr. Soper gave an overview of the Federal Government Safe Drinking Water Act requirements and Water Quality Consumer Confidence Reports. Oro Valley's first Consumer Confidence reports were mailed between 1998 and 1999. In accordance with the Federal Government 1996 Provisions to the Safe Drinking Water Act. -System Operators and Managers are guardians of all drinking water supply and public health. It is also important to communicate to our customers their source of water and they have the right to know by federal law what is in their drinking water. CCRs help consumers make informed choices that affect the health of themselves and their families. Basic CCR Requirements - Customers are interested in a clear statement of the quality of water and any contaminant detected in their water. Several of the Consumer Confidence Report (CCR) requirements are: -Identification of Water Systems: OV System #10-16 and #10-175 -Contact Information, Sources of Water, List of definitions, Levels of detected contaminants and monitoring of any other contaminants, compliance with other drinking water regulations and variances and exemptions -Education information and required language from Environmental Protection Agency (EPA), Explanation regarding contaminants that may be found in drinking water, including bottled water, Statement that informs customer that some people could be more vulnerable to contaminants in drinking water (immune deficiencies, infants and elderly). The CCR must contain basic information about drinking water contaminants, List of drinking Water Rules contaminants (Microbial, Inorganic, Pesticides and Herbicides, Organic chemical and radioactive contaminants). Explanations for each of these contaminants are described in the CCR report. The Consumer Confidence Report also lists Tier 1 through Tier 3 public notice for a monitoring violation. Tier 3 allows the water utility to notify the public within a year of a specific contaminant. The Water Utility is not limited to providing only the required information in the CCR. Other educational information can include the system's diagram, source water protection tips, energy conservation tips, cost of safe drinking water, efforts made to promote "green infrastructure", statement from mayor or general manager, information education about taste 2 . 5/09/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION and odor issues and affiliations with other water programs, other opportunities for public participation. The only limitation on this information is that it must not interfere with the educational purpose of the CCR. Ms. Seng reported that the Consumer Confidence Reports are sent to the State before it is printed and mailed to the public. Mr. Soper indicated that it was a courtesy provided by ADEQ and that they also review all sampling data, federal mandated language and that it coincides with this report. CCR distribution - The majority of the reports are mailed to our customers; however, staff hand delivers numerous copies to each commercial facility in the water service area. Both system reports are posted to the Town's website. Two months after the CCRs are published the utility turns in a signed form to Arizona Department of Environmental Quality (ADEQ) confirming that reports were delivered to the consumers. -Consecutive systems must also receive these reports such as La Cholla Airpark and delivered by April 1. We also print separate reports for Countryside and Oro Valley's water systems. Chair Powell asked a question about consecutive systems such as La Cholla Airpark. Mr. Soper confirmed that consecutive systems supply their customers through one common meter. All CCRs must be kept on file for three years. Mr. Soper gave a quick overview of the Water Quality Monitoring program. Monitoring frequency is determined by contaminant type, population, water source, number of "points of entry", historical data and additional monitoring for operational data and unregulated contaminants. Mr. Soper also explained when a new well such as Well El B is put on line the utility must perform a "new source sampling" as mandated by the federal government. Mr. Soper explained that an analysis must be performed by a State certified laboratory, State can issue violation(s): MCL Violation (Maximum Contaminant Level), Failure to monitor and notify other violations. All violations must be published in CCRs. The Utility had 5,891 analytical results in 2010. The Water Quality area also assists with customer problems. Questions and answer session occurred. -Commissioner Milkey asked about the differences in Countryside's list of contaminants table versus Oro Valley's system. Mr. Soper explained that the only difference was probably water value and sampling within the Countryside area. There is also a difference in the size of Countryside system and sampling points. Mr. Soper explained that the Utility is looking at a different format for the CCRs reports next year. We will also probably add some conservation tips. Mr. Soper mentioned that the contaminants listed on the tables were the only ones detected. 3 w 5/09/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION Mr. Soper described Water Quality's daily schedule for routine monitoring and testing. -Chlorine residual levels are checked at 14 different "end point" locations, on a monthly basis, Total Coliform bacteria samples are taken throughout the whole month, Well site samples must be taken. Some are due annually, quarterly, every three years or every nine years depending on the historical data. Baseline sampling is also performed at the end of every month to establish a water quality history. Chair Powell asked if other water entities regularly send their reports to ADEQ before mailing. Mr. Soper was not certain but mentioned that most utilities would probably send their reports to ADEQ before publishing them. There were no further questions, Mr. Soper ended his report. No action was required on this item. Ms. Seng acknowledged Mr. Soper and his Staff for their excellent water quality sampling. She explained that coliform samples could easily be contaminated by touch, dust, windy days or laboratory errors. She pointed out the Utility has not had a violation in the past 9 years. Chair Powell thanked Mr. Soper for his presentation 3. UPDATE ON INTERIM DELIVERY OF CENTRAL ARIZONA PROJECT WATER (P. Saletta) Discussion and/or possible action regarding the discussions and negotiations with Tucson Water to develop and Intergovernmental Agreement for the delivery (wheeling) of Oro Valley's Central Arizona Project Water through the Tucson Water system. Discussion will also include an update on project activities and schedule. Click here for Item #3 Schedule for Tucson Water Wheeling CAP Mr. Saletta gave an update on Interim delivery of CAP Water through Tucson Water. He also mentioned that the Commission recommended that Council move forward with the IGA negotiations. CAP Interim Delivery System Map - An explanation was given locating the CAP canal. The canal runs through Marana, 1-10 near Tangerine Road, southwest, southeast to west side of Tucson. Mr. Saletta pointed out the Tucson Water recharge facilities at Central and Southern Avra Valley and that our CAP water will be delivered to those locations for recharge. Once recharged the CAP water is pumped from nearby recovery wells and then pumped to Tucson Water's Clearwell Reservoir. Mr. Saletta also explained that the average depth to the groundwater table is about 300 feet. Mr. Saletta explained that from this reservoir it is gravity fed to the north part of town and Tucson Water's Oasis reservoir, and then pumped to Tucson's Water Naranja C-zone reservoir at Naranja and Shannon. Councilmember Hornat asked, are we really going to get groundwater and will there be 4 5/09/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION mixing issues? Mr. Saletta explained that our CAP water is recharged into the groundwater table and pumped back out as groundwater. In answer to Councilmember Hornat question regarding Tucson Water's treatment of CAP water. Mr. Ruiz explained Tucson Water's soil aquifer treatment process together with chlorination and pH adjustment made at the Hayden Udall plant before its delivery into the distribution system. Our need for renewable water is due to declining water levels and to protect and preserve our aquifer. We are over pumping our aquifer (currently 2100 AF per year). It will also help meet Assured Water Supply requirements and reduce our reliance on Central Arizona Groundwater Replenishment District (CAGRD). This project will deliver "wet" water not "paper" credits and we will continue to build Long-term Storage Credits. CAP Delivery Short-term Options - Review the 1,500 AF Preferred Option. The 3,000 AF Option is a significant capital cost about $6.0 to $8.0 million. The 1,500 AF project will cost about $500,000 which is a reasonable capital cost with the possibility of a 5 or 10 year agreement with Tucson Water. Moving forward on parallel tracks: o Negotiate IGA o Permitting o Public Information o Design Mr. Saletta explained there would be the need to do some Arizona Department of Water Resources permitting requirements with respect to storing in the Tucson Water facilities. There is the possibility of permitting through Arizona Department of Environmental Quality. Public Information Plan - Ms. Seng reported that it will be important to keep customers and Town staff updated as this project moves forward. -Billing inserts, press releases, open house, electronic media (Water Utility website updates, Town's monthly newsletter Oro Valley Vista and Talk of the Town's monthly newsletter for town staff. Staff will also welcome suggestions from the Water Utility Commission. An Open House could take place September or October 2011. Chair Powell asked, are we prepared to answer customer questions about this particular insert and who will be contacted? Ms. Seng explained that Customer Service will be informed that all questions should be directed to her, Mr. Saletta or Mr. Ruiz. Ms. Seng pointed out that the first mailing insert will be sent out at the end of May and first week in June. Commissioner Milkey was concerned about having a quorum for the June 13th Commission meeting. Chair Powell confirmed his attendance. Mr. Saletta stated that he would 5 5/09/2011 MINUTES, ORO VALLEY WATER UTILITY COMMISSION coordinate with the Commissioner's schedules and that they could participate by phone. Mr. Saletta also indicated that he would contact the Commissioners via email to assure there was a quorum. Mr. Ruiz reported that Tucson Water will design the pumping equipment and piping inside Tucson Water's Naranja Reservoir site to a common point 10-feet on the outside of their perimeter wall. Mr. Ruiz also explained Oro Valley will design the conveyance pipeline from outside of Tucson Water's perimeter wall approximately 1,000 feet to a connection point with Oro Valley's E zone system located in Naranja Road, and that Oro Valley Water Utility will have full control of the new pumping equipment and will maintain RTU and antenna.
